ONDON (AFP) - - Russia's Dmitry Medvedev hailed Barack Obama as "my new comrade" Thursday after their first face-to-face talks, saying the US president "can listen" -- even if little progress was made on substance. The Russian president contrasted Obama as "totally different" to his predecessor George W. Bush, whom he blamed for the "mistake" of US missile shield plans fiercely opposed by Moscow.
